In Eve, ECM (Electronic Counter-Measures) modules (like Jammers), don't work on NPC pirates (as I once found out the hard way). But looking at EVEMon - it seems that ECM is a subset of the EW category. And there's a lot of different EW (Electronic Warfare) type of modules, like Target Painters, etc.

Do any of these EW modules work on NPCs? (Or the EW drones?) Or are NPCs just immune to everything in the EW category?
